Main-streaming participatory and cross-disciplinary approaches in animal science research in developing countries

  Conventional research approaches have lost considerable momentum after their astonishing achievements during the green revolution. The negative side of focusing rigorously on production improvement was eminent around 1980 and led to considerations of environmental, gender and equity aspects - making agricultural development much more complex than previously. In the search for new ways of addressing the...

Hepatomodulatory role of Enicostemma littorale Blume against oxidative stress induced liver injury in rats

  The hepatomodulatory response of ethanol extract of Enicostemma littorale Blume was examined in contrast to oxidative stress-induced liver injury by carbon tetrachloride (CCl4) in albino wistar male rats. The rats received the extract, orally at the doses of 125, 250 and 500 mg/kg b wt/day for 21 consecutive days and CCl4, at the dose of 0.2 ml/kg b wt/twice a week, i.p with olive oil, in the ratio...

Utilization of phosphorus from different sources by genotypes of promiscuous soybean and cowpea in a low-phosphorus savanna soil

  The differential ability of genotypes of soybean (Glycine max) and cowpea (Vigna unguiculata) to thrive under low-phosphorus (P) conditions by utilising P from sources with low solubility was assessed in a greenhouse study with a low-P savanna soil collected from a research field in Fashola, south-western Nigeria. The P sources added (21 mg P kg-1 soil) were calcium phosphate (Ca-P), iron phosphate...

The role of eggs inoculum level of Meloidogyne incognita on their reproduction and host reaction

  Two pot experiments were separately conducted to determine the influence of four or three inoculum levels (0, 250, 500 and 1000 or 0, 1000 and 2000 nematode eggs/ 850 g soil/pot) ofMeloidogyne incognita on population density of the nematode and host reaction of two solanacious plants viz tomato cv. Castle rock or pepper cv. Anaheim under partly controlled greenhouse at 23 ± 4oC. Nematode...

Chronic toxicity of essential oils of 3 local aromatic plants towards Sitophilus zeamais Motsch. (Coleoptera : Curculionidae)

  The maize weevil, Sitophilus zeamais is a major stored grain pest currently controlled by chemical pesticides. This commonly used control method to prevent post-harvest losses leads to pollution of the environment and intoxication of consumers. Essential oils of aromatic plants are more considered as good control alternative tools. The amount of active volatile of essential oils present in granaries...

Potential of Anisopteromalus calandrae (Hymenoptera: Pteromalidae) as biocontrol agent of Callosobruchus maculatus (F.) (Coleopetera: Bruchidae)

  The bruchid Callosobruchus maculatus (F.) (Coleopetera: Bruchidae) is a major pest of stored cowpea Vigna unguiculata (Walp.) in Africa and particularly in northern Cameroon.Anisopteromalus calandrae (Hymenoptera: Pteromalidae) parasitoid of its larval stages, could be used in the biological control of this grain pest. In field conditions, 5 months samples in small holder...

Persistence of insecticidal activities of crude essential oils of three aromatic plants towards four major stored product insect pests

  Essential oils of aromatic plants with insecticidal properties are more and more considered as alternative insecticides to protect stored products. Many banned insecticides have high persistence which allow them to occur at several levels of trophic chains. The aim of the present work is to analyse the persistence of insecticidal activity of crude essential oil of three most used local aromatic plants...

Survey of the post harvest diseases and aflatoxin contamination of marketed pawpaw fruit (Carica papaya L) in South Western Nigeria

  Survey and collection of the marketed pawpaw fruit with rot symptoms were conducted in the South Western Nigeria in 2000 and 2001 respectively.  Pawpaw fruits showing rot symptoms that are displayed for sale in three different market places in three major cities in south western Nigeria namely, Ibadan, Abeokuta and Akure were collected and examined for the presence f the inducing pathogens and for...

Levels of variability in groundnut (Arachis hypogaea L.) to cercospora leaf spot disease – implication for selection

  Groundnut (Arachis hypogaea L.) is an important crop both in subsistence and commercial agriculture in arid and semi-arid regions of the world. Leaf spot diseases caused by fungus have been a major destructive disease of groundnut and could cause a yield loss of up to 50 % or more. A two-year experiment was conducted during the cropping seasons of 2002 and 2003 at the Faculty of Agriculture Research Farm,...

Seromonitoring of especially dangerous diseases in small ruminants in the Republic of Tajikistan

  Seromonitoring for antibodies against especially dangerous viral infections in small ruminants in the Republic of Tajikistan was conducted. Antibodies to sheep pox and PPR viruses were detected in blood sera of small ruminants.   Key words: Virus, antigen, enzyme-linked immunosorbent assay, sheep pox, peste des petits ruminants.

Application of para-wood charcoal as the media of the vertical-flow constructed wetland for treatment of domestic wastewater

  The research aimed to observe the efficiency of vertical flow constructed wetland (VFCW) system using Para-wood charcoal as the media and Typha sp. as the cultivating plant to treat domestic wastewater. The removal efficiency was increased with the increase of HRT or decrease of hydraulic loading. And the size of Para-wood charcoal media (1, 3 and 5 cm in diameter) did not show any effect to...

Control of ochratoxin A (OTA) in kunu zaki (a non-alcoholic beverage) using DaniellinTM

  Kunu-zaki, a non-alcoholic beverage, was produced using modified traditional method incorporating DaniellinTM.  Treated samples kept for 5 days at ambient condition (26+-2 C) while untreated samples kept for only 1 day. Protein contents and calorific values of kunu-zakitreated with DaniellinTM (0.5 to 5.0%, w/v) were between 5.76 to 5.93% and 1606.47 to 1626.8 KJ/100g while values for...
